Answer: No. If you did consistently avoid these foods for any extended period, your health would likely suffer as all of these foods provide many benefits to the human system.
Fruit has fiber, antioxidants and phytochemicals that reduce the incidence of certain types of cancer, heart disease and free radical damage. Whole wheat products provide insoluble fiber that can aid in glucose and calorie control, satiety, regularity and reduced risk of certain cancers. Dairy products, especially low-fat versions, are a great source of protein, calcium, vitamin D and A. So eat these foods and keep your calorie intake at a level that supports your goal – remember that weight loss is all about calorie balance. For more on calorie balance, see Weight Control 101.
